Der Erfindung liegt die Aufgabe zugrunde, ein Kraftstoffsystem für zwei in getrennten Vorratsbehältern gespeicherten Kraftstoffen mit Kraftstoffversorgung und Kraftstoffumschaltung für direkteinspritzende Ottomotoren zur Verfügung zu stellen.The invention has for its object to provide a fuel system for two stored in separate reservoirs fuels with fuel supply and fuel switching for direct-injection gasoline engines available.
Diese Aufgabe wird erfindungsgemäß durch eine Kraftstoffhochdruckpumpe der o. g. Art mit den in Anspruch 1 gekennzeichneten Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben.This object is achieved by a high-pressure fuel pump o. G. Art solved with the features characterized in claim 1. Advantageous embodiments of the invention are described in the further claims.
Dazu ist es bei einer Kraftstoffhochdruckpumpe der o. g. Art erfindungsgemäß vorgesehen, dass die Kraftstoffhochdruckpumpe eine Mitteldruckkraftstoff-Vorlaufkammer und einen Mitteldruckkraftstoffanschluss, welcher in die Mitteldruckkraftstoff-Vorlaufkammer mündet, zum Zuführen von Mitteldruckkraftstoff an die Kraftstoffhochdruckpumpe aufweist, wobei ein Kraftstoff-Umschaltventil derart angeordnet und ausgebildet ist, dass das Kraftstoff-Umschaltventil wahlweise die Niederdruckkraftstoff-Vorlaufkammer oder die Mitteldruckkraftstoff-Vorlaufkammer fluidleitend mit dem Pumpenelement verbindet.For this it is in a high-pressure fuel pump o. G. Art provided according to the invention that the high-pressure fuel pump has a medium-pressure fuel supply chamber and a medium-pressure fuel port, which opens into the medium-pressure fuel supply chamber for supplying medium pressure fuel to the high-pressure fuel pump, wherein a fuel switching valve is arranged and configured such that the fuel switching valve selectively Low-pressure fuel supply chamber or the medium-pressure fuel supply chamber fluidly connected to the pump element.
Dies hat den Vorteil, dass eine vereinfachte Umschaltung zwischen einem Mitteldruckkraftstoff, wie beispielsweise LPG, und einem Niederdruckkraftstoff, wie beispielsweise Benzin oder Ottokraftstoff, die auf unterschiedlichen Druckniveaus arbeiten, zur Verfügung steht. Hierbei ist eine nur noch minimale Mischung beider Kraftstoffarten nach einer Umschaltung gewährleistet, da die Kraftstoffe direkt vor dem Hochdruckpumpenraum vorgewählt werden.This has the advantage of providing a simplified switch between a medium pressure fuel such as LPG and a low pressure fuel such as gasoline or gasoline operating at different pressure levels. In this case, only a minimal mixture of both types of fuel is guaranteed after a switch, since the fuels are pre-selected directly in front of the high-pressure pump room.
Eine einfache und genau Mengensteuerung des von dem Hochdruckanschluss abgeführten Kraftstoffes erzielt man dadurch, dass zwischen dem Pumpenelement und dem Kraftstoff-Umschaltventil ein Mengensteuerventil angeordnet ist.A simple and accurate quantity control of the discharged fuel from the high-pressure port is achieved in that a quantity control valve is arranged between the pump element and the fuel switching valve.
Eine besonders effektive Zuführung von Kraftstoff erzielt man dadurch, dass der Hochdruckanschluss zum fluidleitenden Verbinden mit einem Common-Rail der Brennkraftmaschine ausgebildet ist.A particularly effective supply of fuel is achieved in that the high-pressure port is designed for fluid-conducting connection to a common rail of the internal combustion engine.
Zum Herstellen eines kontinuierlichen Stromes von Mitteldruckkraftstoff durch die Kraftstoffhochdruckpumpe, so dass sich eine entsprechende Kühlwirkung ergibt, ist mindestens eine Rücklaufleitung für den Mitteldruckkraftstoff vorgesehen, die mit der Mitteldruckkraftstoff-Vorlaufkammer fluidleitend verbunden ist.For producing a continuous flow of medium pressure fuel through the High-pressure fuel pump, so that there is a corresponding cooling effect, at least one return line for the medium-pressure fuel is provided, which is fluid-conductively connected to the medium-pressure fuel supply chamber.
Eine universell für beide Kraftstoffarten verwendbare Rücklaufleitung stet dadurch zur Verfügung, dass mindestens eine Rücklaufleitung vorgesehen ist, die stromab des Kraftstoff-Umschaltventil und stromauf des Pumpenelementes abzweigt.A universally usable for both types of fuel return line stet thereby available that at least one return line is provided, which branches off downstream of the fuel switching valve and upstream of the pump element.
Ein unerwünschtes Verdampfen des Mitteldruckkraftstoffes aufgrund eines Druckabfalls ist dadurch verhindert, dass in der Rücklaufleitung ein hydraulischer Widerstand angeordnet ist, welcher derart angeordnet und ausgebildet ist, dass stromauf des Widerstandes ein vorbestimmter Druck für den Mitteldruckkraftstoff herrscht.An undesirable evaporation of the medium-pressure fuel due to a pressure drop is prevented by the fact that in the return line, a hydraulic resistance is arranged, which is arranged and designed such that upstream of the resistance prevails a predetermined pressure for the medium-pressure fuel.
Einen Betrieb der Kraftstoffhochdruckpumpe mit herkömmlichen, überall erhältlichen Kraftstoff erzielt man dadurch, dass der Niederdruckkraftstoff ein Kraftstoff ist, welcher bei einem Druck von 4 bis 6 bar flüssig ist, insbesondere Ottokraftstoff.An operation of the high-pressure fuel pump with conventional, widely available fuel is achieved in that the low-pressure fuel is a fuel which is liquid at a pressure of 4 to 6 bar, in particular gasoline.
Einen Betrieb der Kraftstoffhochdruckpumpe mit besonders kostengünstigem Kraftstoff erzielt man dadurch, dass der Mitteldruckkraftstoff ein Kraftstoff ist, welcher bei einem Druck von 20 bis 30 bar flüssig ist, insbesondere Autogas oder LPG (Liquefied Petroleum Gas).An operation of the high-pressure fuel pump with particularly inexpensive fuel is achieved in that the medium-pressure fuel is a fuel which is liquid at a pressure of 20 to 30 bar, in particular LPG or LPG (Liquefied Petroleum Gas).
Eine besonders funktionssichere und langlebige Kraftstoffhochdruckpumpe mit hohen Ausgangsdrücken bei gleichzeitig kostengünstiger Fertigung erzielt man dadurch, dass das Pumpenelement eine Kolbenpumpe ist.A particularly reliable and durable high-pressure fuel pump with high output pressures while cost-effective production is achieved by the fact that the pump element is a piston pump.
